Actually no, it's not really normal behavior. And if she truly cared she'd bring you along with her to these meetings, discuss the sms/phonecalls with you, and generally be a lot more open about involving you in her relationship with him.
I would be concerned. Especially since he has to keep it from his girlfriend. That is a sign of active secrecy on his part.
